TABLE FOR BRUSH-FILLING MACHINES.

` Application filed December 15, 1916. Serial No.

T0 all whomz't may concern.' v

Be it known that I, LEONARD B. TERHUNE, of Newark, in the county of Essex, and in the State of New Jersey, have invented a certain new and useful Improvement in Tables forBrush-Filling Machines, and do hereby `declare that the `following is a full, clear, and exact description thereof. My invention relates particularly to tables adapted to support brush blocks when being filled with tufts of bristles, though it is adapted also for other uses.

The object of my'invention is to provide a table for brush machines which is of a yielding nature so that it `will automatically oompensate for variations in the depth ofthe holes in the brush block, also for inaccurate adjustments in the height of the brush table, as well as the stroke of the needle and for variations in the thicknesses of the brush blocks.

The table made in accordance with my invention is especially applicable for use in connection with brush filling machines, such as those shown in the patent to Liebig, No. 846,583, March 12, 1907, although it is also applicable for use in connection with other brush machines. j

While my invention is capable of embodi` ment in many different forms, for the purpose of illustration I have shown only one form thereof in the accompanying draw ings, in which,

Figure 1 is a side elevation of a table made in accordance with my invention; and

Fig. 2 is an end elevation of the same.

In the drawings I have shown a frame 1 of a brush machine to which there is attaohed a bracket2by screws 2a. The bracket 2 has a split bearing 3 provided with wings 4, arranged to be pressed together by a screw 5 for holding in place a vertically movable elevating rod 6 which is splined in the bearing 3.` The bracket 2 has, furthermore, a downwardly directed arm 7 provided with a bearing 8 for receiving the elevating rod 6. Said rod 6 is screw-threaded and between the bearings 3 and 8 there is a hand-wheel 9 screw-threaded on the rod 6. The handwheel 9 rests upon a flanged-sleeve 10 which is received in the bearing 8k around the rod 6 and on said rod 6 there is, furthermore, a washer 11 located below the bearing 8 and in contact with the lower end of the sleeve 10. Around the rod 6 there is also provided Speciieation of Letters Patent.

with the journal bracket 28a.

a spring 12 adjacent to the washer 11.v Said spring rests against an adjustable abutment 13 held in place by nuts 14 on a screw-` threaded rod ltrl extending downwardly from the arm 7 At its upper end the elevating rod 6 is y provided with four arms 14a, 15, 16 and 17.

The arms 14:l and 15 are longer than the arms 16 and 17 and are connected together by a shaft 18 provided at its outer ends with two flanged rollers 19. The shorter arms 16 and 1 7 are connected together by a shaft 20 carrying on its outer end two additional flanged rollers 21. Outside of the flanged rollers 19 and 21 there are two bracing bars 22 and 23. Screws 24 retain the bars 22 and 23 on the ends of the shafts 18 and 20. A sliding carriage 25 is supported upon the rollers 19 and 21 by means of curved tracks `26 and 27. The track 27 has a pivoted hand lever 28 thereon supported in journal brackets 28a and provided with a pin 29 in its end to coperate with a series of holes 30 in the bracing bar 23. As shown in Fig. 1 the bracing plate 22 has an upwardly directed extension 31 near one end thereof which acts partly'as a guide for the sliding carriage 25 and as a stop for the same by coperating The carriage 25 has screw-threaded thereto a rotary table 32 carried upon a screw-threaded rod 33. As shown in Fig. 1 the table 32 is designed to support a brush block 34 in which tufts 35 of bristles are to be inserted from a nozzle 36 of a brush machine, the details of which are not shown.

In the operation of my invention the brush block 34 having been applied to the table 32, the brush blockis located at the desired angle by releasing the hand lever 28 and inserting the pin 29 thereon in the proper hole 30. This adjustment of the angle may be accompanied by a rotation of the table 32 on the screw-threaded bar 33 to produce the exact inclination desired in the particular hole in the brush block 34 to be filled. Upon the operation of the nozzle 36 carrying a tuft of bristles to be inserted the nozzle 36 will come into contact with the brush block 34 and depress the elevating rod 6 within the limits of movement permitted by the flanged sleeve 10 and the washer 11 in opposition to the force of the spring 12, thus automatically compensating for variations in the depths of the holes in the brush block,

also inaccurate adjustments in the height of the brush table, as well as the stroke of the needle and variations in the thicknesses of the brush blocks. The extension 31 upon the bracing bar 23 acts as a stop for the bracket 28a and therefore for the carriage 25. Ad* justments in a vertical direction may `be made by the hand wheel 9, and adjustments for the force of the spring 12 may be made by means of the nuts 14.

While I have described any invention above in detail, I wish it to be understood that many changes may be made therein without departing from the spirit of my invention.

ably receiving 'the' same, an adjusting wheel for said rod located between said wings, a sleeve disposed in one of said wings, a fixed abutment, and a spring compressed between said sleeve and said abutment to form a yielding` support for the rod.

3. In combination, a table supporting rod, a fixed bracket slidably receiving the same, a sleeve inclosing said rod and located within said bracket, a fixed abutment, a spring surrounding said rod and compressed between said sleeve and said abutment to form a yielding support for the rod.

4. In combination, a table supporting rod, a fixed bracket slidably receiving the same, a fixed abutment, a spring surrounding the lower end of said rod and compressed by A' said abutment to form a. yielding support for the rod.

5. In combination, a table supporting rod, a bracket slidably receiving the same, a fixed abutment, a fixed spring surrounding the 1 lower end of said rod and compressed by said abutment to form a yielding support for the rod, and means for varying the compression of said spring.

.In testimony that I claim the foregoing I have hereunto set 4my hand. Y
